Hi,

Please run the following command tom check the room mailbox calendar configuration and folder permission:

Get-CalendarProcessing -Identity RoomA | fl

Get-MailboxFolderPermission -Identity RoomA:\Calendar | fl

Please confirm whether these organizers have the special permission to this room calendar.

Regards,

We have a ton of room mailboxes and we have them set to delete the original subject and add the organizer's name to the subject. We have 1 room mailbox that it's working fine on for 95% of the appointments, but a few appointments on that same room mailbox are showing as the person's original subject. Not sure why. Has anyone ever seen this?

When I run the get-mailboxfolderpermission 'mailbox:calendar', the only thing that is listed is Anonymous which is set to none, and "Default" which is set to LimitedDetails, which is only so the other users can view the subjects of the meeting requests.

The get-calendarprocessing is below

Check the calendar permissions with get-mailboxfolderpermission 'mailbox:\calendar' and see if anybody has the ability to create appointments directly in the calendar. When you add a delegate to a room for example, they receive editor permissions.

Hi,

According to your further posting, the room mailbox configuration in server side seems to be correct. Please narrow down the issue to the client side which can view the original subject instead of the Organizer as the subject.

The folder permission is proper, please run the following command to confirm whether this user has full access mailbox level permission:

Get-MailboxPermission -Identity Boardroom | fl

In client side, please remove the room Calendar from Outlook and add it back in Online mode to check whether the original subject is visible or not.

Regards,
